MACHINE FOR PRINTING AND CUTTING STEPPED INDEXES.

SPECIFICATION forming part of Letters Patent No. 351,249, dated October 19,1886.

Application filed June 1, 1885. Serial No. 167,255. (No model.) Patented in England April24, 1884, No. 6,777.

To all whom, it may concern.-

Be it known that we, ALEXANDER SINCLAIR CocHILL and JOHN ALEXANDER CAMERON RUTHVEN, subjects of the Queen of Great Brit ain, residing, respectively, at Moyne Road, Rathmines, and at Tritonville Road, Sandymount, both in the county of Dublin, Ireland, have invented a new and useful Machine for Cutting and Printing Stepped Indexes, (for which we have obtained a patent in Great Britain, No. 6,777, dated April 24, 1884,) of which the following is a specification.

Our invention relates to a machine for cutting stepped indexes and printing on the successive steps successive letters, which may be of two different colors.

Ve mount on a suitable frame a sliding table, to which, by means of a treadle working a pawl-and-ratchet motion, a step-hy-step movement is given, each step constituting an equal advance. In order to adjust the advance made at each step to be an equal division of the depth of a page, whatever the total depth may be, we connect the table to a lever to which the step-by-step motion is given at various distances from its fulcrum, so that the advance of the table at each step which the lever makes is proportional to the distance of the connection from the fulcrum of the lever. Above the table we mount in suitable guides, at some distance apart, two vertically-sliding bars, which are caused to reciprocate by the action of the same treadle that moves the lever step by step, these bars ascending while the pawl is advancing the ratchet that moves the lever, and descending when the pawl is making its back-stroke. To one of these bars is attached the cutting-punch, which in descending cuts a step from the edge of the paper placed on the table below it. To the other bar is attached a type-wheel with suitable inking apparatus, this wheel having on its axis a ratchet-wheel that at every ascent of the wheel turns it one division round. when the typewheel descends, the type presented at the lowest point impresses a letter on the paper placed on the table below. Thus an operator holding the pages of the index, filed or bound together, under the cutting-punch, has them cut into successive steps, and the step-cut pages, being fixed under the type-wheel, each step is printed with its appropriate letter.

VVhe'n it is desired to print the letters in two colorsas, for example, red and blue, alternating-we make the type-wheel with two rows of types side by side around its periphery, and by means of a helical guide cause the type-wheel to turn during each ascent half round the axis of the bar on which it is mounted, so that the types of the two rows are presented alternately to the paper. Each row has in that case its separate inking-roller, one for each color.

Figure l of the accompanying drawings is a front view of a machine according to our invention. Fig. 2 is a plan with part of the table broken away to show some of the mechanism below it. Fig. 3 is a transverse section. Fig. 4 is a front view, and Fig. 5 a side View, partly in section to an enlarged scale, of the double type wheel and inker. Fig. 6 is a de tail perspective view of the means employed for operating the pawl-bar, and Fig. 7 is a detail perspective view of the means employed for turning the type-wheel.

A is the table, having at one part of its length a channel, a, faced with soft metal to receive the stroke of the cutting-punch, the stem of which works up and down in the head B, being made to descend by the downstroke of the treadle O, which is counterweighted at o. The downstroke of the treadle also causes descent of the type-wheel D, the stem of which works in the head E. By means of a rocking shaft, F, and its arms the stroke of the treadle also moves a bar, G, carrying a spi-ingpawl, g, which engages with a ratchet-rack on another bar, H, moving it step by step to the left at each upstroke. The bar H, by means of a pin, h, moves a two-sided lever, K, pivoted at K, between the sides of which lever can be slid, by means of a screw, another pin, 70, which engages in a transverse slot on the under side of the table A. By shifting the pin in along its slot the advance imparted to the table at each upstroke of the treadle can be adjusted to suit various lengths of index;- steps.

It is apparentthat the ratchet-bar H always gives the lever K astroke of definite length,

and that the degree of movement is'varied by adjusting the pin la, which engages in a transverse slot in the under side of thetable, and is moved by a horizontal set-screw. Obviously thenearer the pin 70 is to the pin h on the rackbar H the more nearly does the stroke of the table agree with the stroke of said rack-bar, and the farther la is from h the greater is the leverage with which the lever K acts on the table, and consequently the longer is the stroke of the table.

The stem R of the type-wheel D carries a roller, e, which, by descending and ascending in a helical cam-slot of the head E, causes the stem R of the type-wheel to turn half-round at every stroke.

In Fig. 1 we have illustrated this slot with helically-slop'ing sides with part of the roller 6 shown supported above one of said sides. It is obvious that when the roller e rests on the top of the incline that it cannot come down without turning the stem R, on which it is mounted,partly around, and in going up again it is guided by the inclined tongue projecting down so that it must go farther around, and consequently the same operations must be repeated at the rear side of the head E.

The lower part of R, as shown in Fig. '5, is fitted with a feather to slide through a boss,

Q, which is fitted to turn in the stationary bracket P,but is prevented from moving vertically. From the boss Q a double fork-frame,N

0, projects downward, one fork on each side having rack-teeth m gearing with pinions on arms which carry inking-rollers M. These arms, as Well as a pair of curved inking-segments L L, are carried on a fork-frame, T U,

which projects down from the stem B,and carries also the axis of the type-wheel D, which has on each side a ratchet-wheel, and has on its periphery two rows of types alternating. Pawl-lev-ers d, loaded at d, are pivoted on the forks O, the ends of the levers d being bent so as to engage the ratchet-wheels as they ascend along with the frame T U, thus turning the type-wheel a division at each upstroke of R.

them to return and ink the lowest type presented by the type-whee]. The two segments L being charged with inks of different colors, the types will imprint these colors alternately, each row of types being caused to alternate by the half-revolution of the stem R,-with which also turns half-round the boss Q and the frames N O.

Having thus described the nature of our invention and the best means we know of carrying the same into practical operation, we' claim 1. In a machine for cutting and printing stepped indexes, the combination, with asliding table, of a treadle, a vertically-guided cutting-stem, a vertically-guided printing-stem,

a rocking shaft,with its arms, pawl, and ratcha machine for cutting and printing stepped indeXes, the combination, with the table A, of the ratchet-bar H, its pin h, the lever K, and the pin lo, adj nstable along slots'of the lever K, and of the table A, substantially as described.

.3. For alternating the colors printed by a machine for cutting and printing stepped indexes, the combination of the helically camslotted head E, the printing-stem R, its roller e, and the double-rowed type-wheel D with the double inking-segments L and rollers M, the gears m, and pawls cl, substantially as described.

In testimony whereof we have signed our names to this specification, in the presence of two subscribing witnesses, this 18th day of May, A. D. 1885.
